You will still need a vent in the chimney to prevent damp.

bikeit, Hi.
Both the balloon and the chimney cap are in effect "Off the shelf" bits of kit, Google chimney balloons and there are a range of them available a quick measurement of the chimneys "throat" will allow you to get a correct size for your needs. From time to time it will need to be pumped up a bit as over time they do loose pressure. Watch out for debris, soot Etc. gathering on top of these things [can be messy]
As for the cap, any decent Builders merchant can provide same.
CAUTION ! dampness / condensation WILL occur in a completely Un-Vented Chimney, this can lead to Sulphate attack where a dark stain WILL begin to appear on the outer surface of the wall and at times within the Property as well.
One Idea to prevent the formation of Condensation is to allow ventilation from time to time [but not during periods such as we are going through now] simply deflate the balloon [watching for debris on top of it] then re-inflate the balloon, after a period of time, and because the top cap does have holes in the sides the ventilation will happen.

The balloon does not make an air tight seal and should allow enough air passed to keep things dry.
Wind noise can be reduced with suitable capping vent.

Get a black bag and part fill it with crunched up newspaper then shove up the chimney.
